Abstract

Correction for ‘Superprotonic conductivity in RbH2−3y(PO4)1−y: a phosphate deficient analog to cubic CsH2PO4 in the (1 − x)RbH2PO4xRb2HPO4 system’ by Grace Xiong et al., Mater. Horiz., 2023, 10, 5555–5563, https://doi.org/10.1039/D3MH00852E.


The authors wish to clarify that the atomic displacements reported in Table 1 of the published article correspond to the unitless βiso values. The Uiso values (Å2) for Rb, P, and O are 0.068(2), 0.054(4), and 0.058(4), respectively.

The corrected form of Table 1 is shown here.

Table 1 Fractional atomic coordinates and displacement parameters of α-Rb1+xH2−xPO4 at x = 0.180 and T = 245 °C. Structure adopts space group Pm[3 with combining macron]m with a = 4.7138(2) Å. The P–O bond distance is 1.51(2) Å. Numbers in parentheses reflect the uncertainty in the final digit(s) of the quoted values

The supplementary information of the published article has also been updated accordingly (Tables S4 and S5).

In addition, please note that the grant number DMR-2118201 mentioned in the Acknowledgements section of the published article is incorrect, it should be replaced with OAC-2118201. The corrected version of the Acknowledgements section is given below.
